Mobile ad hoc networks (MANETs) represent complex distributed systems that comprise wireless mobile nodes that can freely and dynamically self-organize into arbitrary and temporary, ‘‘ad-hoc’’ network topologies, allowing people and devices to seamlessly internetwork in areas with no pre-existing communication infrastructure, e.g., disaster recovery environments. Ad hoc networking concept is no...

Traditional ad hoc networks have flat architecture, which suffers from poor scalability. Theoretical analysis and experimental results imply that throughput for each node decreases rapidly toward zero while the number of nodes increases in such architecture. Hierarchical architecture in ad hoc networks present a trade off between cellular networks and pure ad hoc networks, in that data may be f...

‘Secure routing in Mobile Ad hoc networks’ and ‘Internet connectivity to Mobile Ad hoc networks’ have been dealt separately in the past research. This paper proposes a light weight solution for secure routing in integrated Mobile Ad hoc Network (MANET)-Internet. The proposed framework ensures mutual authentication of Mobile Node (MN), Foreign Agent (FA) and Home Agent (HA) to avoid various atta...

It is a great pleasure to introduce this special issue. Multi-hop ad hoc networks are collections of (mobile) nodes connected together over a wireless medium. These nodes can freely and dynamically self-organize into arbitrary and temporary , " ad hoc " network topologies. A mobile ad hoc network (MANET) is probably the most well-known example of this networking paradigm having been around for ...

Mobile multi-hop ad-hoc networks promise an efficient and very flexible way of establishing a communication connection. One aspect of these kind of networks is their convenience, which is sometimes neglected in research. Especially for civil applications, this aspect of ad-hoc networks need more attention. It is expected that users neither need to know much of networks nor perform complex confi...

An ad hoc network is a distributed and self-organized network, where wireless terminals exchange network information with neighbor terminals and construct a multi-hop network. The topology of such a network changes frequently because of the unsettled wireless environment and/or terminal mobility. Consequently, appropriate route maintenance is necessary. In this thesis, we first focus on a comme...

—Ad-hoc networks are basically peer to peer multi-hop mobile wireless networks in which the information packets are transmitted in a 'store and forward' manner from a source to an arbitrary destination via intermediate nodes. The main objective of this paper is to evaluate the performance of various ad-hoc networks routing protocols viz.

Deployed in 1990’s, Mobile Ad-hoc networks have been widely researched for many years. Mobile Ad-hoc Networks are a collection of two or more devices equipped with wireless communications and networking capability. These devices can communication with other nodes that immediately within their radio range or one that is outside their radio range. For the later, the nodes should deploy an interme...
